What happens to communities when the fish disappear? For millions of small-scale fishers (SSFs) worldwide, this isn’t just a question—it’s a daily reality. SSFs support the livelihoods of 120 million people globally, yet these vital ecosystems are on the brink of collapse due to declining water quality, pollution, and climate change.

From modelling floods and droughts to managing watersheds and tracking climate change, today’s environmental challenges require faster, more powerful computing. Now, researchers at the University of Waterloo and across Canada have a new tool to help solve them: Nibi, Waterloo’s newest high-performance supercomputer.

What started as a personal curiosity during a California drought has become a global, interdisciplinary research journey for Isabel Jorgensen, PhD candidate, School of Environment, Resources, and Sustainability - Collaborative Water Program, Water Institute. 

Lake Winnipeg has been experiencing increasingly severe algae blooms since the 1990’s, earning it the title of “Canada’s Sickest Lake”. This “illness” stems from excess nutrients, primarily phosphorus and nitrogen, running off from agricultural lands, urban areas, and wastewater treatment plants. These nutrients result in various water quality problems, including excessive algae growth, which can block light, deplete oxygen levels, and release toxins into the water.

A recent visit to Germany’s Karlsruhe Institute of Technology (KIT) has opened new doors for collaboration between researchers at the Water Institute and colleagues at one of Europe’s top technical universities.

Have you ever been on a “skunked” fishing trip—one where you don’t catch a single fish? Sometimes, it’s the weather. Other times, it’s faulty gear. But if you’ve been fishing in rivers for a while, you may have noticed more and more skunked trips. The problem might not be your technique—it could be the river itself.

Roy Brouwer, Professor in the Department of Economics, University Research Chair in Water Resources Economics, and Executive Director of the Water Institute, has been appointed to the Science Advisory Board – Science Priority Committee of the International Joint Commission (IJC), a binational partnership between Canada and the United States managing shared waters.

On March 22, the Water Institute marked World Water Day—an annual event bringing together students, researchers, and community members to reflect on our relationship with water. This year’s event aligned with the United Nations’ 2025 theme, Glacier Preservation, and featured insightful talks from distinguished speakers, a showcase of emerging research, and a special recognition of alumni driving change in water management.
